' LEVER HOOK Filed April 30, 1932 Patented July 10, 1934 PATENT OFFICE 1Claim.

The invention relates to improvement in door hooks. The old typegenerations old has never satisfactorily fastened a door. It has beenimpossible to pull the door into position by grasping the hook as nopurchase could be had to pull it tight. In attempting to do this manyminor accidents have happened such as laceration of the hands. Hencemany doors such as rolling barn doors have been neglected and allowed torattle and slam, also allowing rain and snow to get through theopenings.

In the accompanying drawing forming part of this specification,

Figure l is a front elevation of my improved lever hook in appliedposition, and

Figure 2 is a cross section taken on the line 22 of Figure 1.

Referring now to the drawing in which like characters of referencedesignate similar parts in the various views, 10 designates a door frameand 11 a door, these parts being of the usual and well knownconstruction.

In carrying out the invention, I provide an elbow lever l which may beformed of strap metal. The long arm of the lever forms a grip or handle,while the short arm of the lever extends at an acute angle from theelbow of the lever with respect to the handle and is provided with ahook 2. The lever is pivotally mounted upon a wear plate 3 which isattached to the door frame by means of a screw 4 or similar connector.The lever is fulcrumed on a screw 5 or similar connector passed throughthe short arm of the lever between the elbow of the lever and theextreme end of the short arm. The screw 5 is passed through the wearplate 3 and into the door frame. A keeper 6, such as a staple or a screweye, is secured to the door 11 to be engaged by'the bill of the hook 2.The handle of the lever 1 engages a stop screw or similar connector '7when rocked to vertical position to hold the hook 2 01f center andfirmly engaged in the keeper 6.

More specifically, the wear plate 3 may be an ordinary washer throughthe center hole of which is passed the securing screw 4. The fulcrumscrew 5 of the elbow lever is disposed laterally of the screw 5 so thatit will be particularly observed, the elbow of the lever extends overthe screw 4 of the wear plate when the lever is in the operative fullline position shown in Figure 1 and positively prevents loosening of thescrew and wear plate. By virtue of the fulcrum 5 being disposed betweenthe elbow of the lever and the extremity of the short arm thereof, saidextremity will dispose the hook 2 oif center when in operative positionso that pull of the keeper, due to the tendency of the door to open,upon the hook 2 will hold the handle of the lever l tightly against thestop 7 and positively prevent accidental dislodgment until the handle ismanually rocked to released position.

Preferably, the extreme end of the short arm of the elbow lever is offset, as shown at 8 in Fig. 2, and is perforated to receive the abruptlybent end 9 of the hook, said end being terminally headed up, as shown at12, to permit the hook to swivel freely. The offset end 8 of the leverpermits of sufiicient clearance between said offset end and the doorframe to prevent the hook from binding against the door frame when thelever 1 is manipulated.

When the lever is lifted the hook will reach out as much as two inches.The hook will engage staple or screweye. Then upon pressing down on thelever it will bring the door into position and close it so tightly thatall of the old time annoyances are eliminated. As the lever descends itpasses a centre, and locks itself into position by striking stop 7 asindicated.

The stock size of this device is lever 8 in. hook 4 in. but may be madein any size. It is also made in rights; and lefts to accommodate doorsopening accordingly.

I clam:

The combination with a door and its jamb, of a staple carried by thedoor, a fiat washer on the jamb forming a wear plate, a securing screwpassed through the center of the washer into the jamb, a substantiallyJ-shaped elbow lever movable over the wear plate and having a long armforming a handle and a short arm extending from the elbow at an angle tothe handle and having its free end ofiset laterally to form a perforatedseat at the rear of said short arm, a pivot pin independent of thewasher securing screw passing through the short arm into the washer atone side of said washer securing screw, a latch hook adapted to engagethe staple and having one end thereof bent laterally and extendedthrough the perforation in the seat and provided with an enlargedterminal head fitting in said seat with the rear face of the headdisposed in advance of the rear face of the elbow lever, and a stop pindisposed on the jamb and forming an abutment for the handle when saidhandle is in a vertical operative position.
